Big Karan amps

I have heard the entire line of these bad boys and they are truely spectactular. In my humble opinion, they are the finest solid state amps available at any price. They are liquid smooth and have gobs of class A power and do not run hot. I will eventually buy the kam 1200 monblocks when I have 45K to burn. OF all the brands you mentioned, I owned the BAT vk 600s, the thetas, and the Burmester, as well as the big mac mc 1201's as well as clayton audio m-300's if that helps. The karans don't get much hype here because they probably don't kick back anything to the reviewers hence they seldom get reviewed. I am not affiliated with any of these brands and have owned them for a period of time with various speakers but nothing in solid state moved me like the karans. They are almost tubelike without all the fuss and have incredible head room to drive anything. Hope this helps

I had the citadels and I found them a little more accurate than the bat 600s, a little more sterile and not as warm. I think the karan smokes them all by a large margin

While I agree with Rtn1 about the midrange and their power I disagree somewhat on what he says about their bass, speed, and slam. I think they are incredibly fast but more liquid in their presense. I think their sound is more accurate or real where krell is in your face and colored. I have owned krell solid state on and off for over 15 years and it has been love at first site and than I lose interest after a month or so. The Karans truely do something magical and correct. IF you want musical nirvana, hook the karan 1200 monoblocks up to a pair of Avalon ISIS and you will never have to buy anything again. Another great match is with the coincident pure reference speakers. I know it's over kill but man was that setup magical.
